Problems solved by technology

However, chromate has certain toxicity, and the use of phosphate will produce a large amount of phosphorus-containing waste liquid. The cost of waste liquid treatment is very high, causing great harm to human health and the environment, and the treatment effect is poor. , does not meet the requirements of modern society for environmental protection
As an improvement, the metal surface treatment agent of zirconium ion, titanium ion and fluoride ion is also disclosed in the prior art, but the corrosion resistance of this type of metal surface treatment agent can not reach the level of chromium metal surface treatment agent, and, also It cannot solve the requirement of protecting the wear resistance while being resistant to corrosion

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an environment-friendly metal surface treatment agent and a preparation method thereof. Background technique [0002] Materials are an indispensable part of human survival and life, the material basis and forerunner of human civilization, the driving force that directly promotes social development, and the indispensable material basis for improving people's living standards. Therefore, materials are closely related to people's lives. Among them, metal materials have become one of the most widely used materials because of their luster, ductility, easy conduction, heat transfer and other properties. However, this material often undergoes different degrees of oxidation, corrosion, etc. during processing, handling and use, which reduces the service life of metal materials or metal equipment. Therefore, it is necessary to treat the surface of metal materials to increa...
